If the point (2,\ -2) lies on the graph ...

If the point `(2,\ -2)` lies on the graph of the linear equation `5x+k y=4` , find the value of `k`

Text Solution

Verified by Experts

The point `(2,\ -2)` lies on the graph so it satisfies the given equation
putting `x=2and y=-2`
`5x+k y=4`
`5(2)+k(-2)=4`
`10-4k=4`
`k=3/2`
